Absence of Lamin A/C Gene Mutations in Four Wiedemann-Rautenstrauch Syndrome Patients

The Wiedemann-Rautenstrauch syndrome (WRS, OMIM: 264090) characterizes a premature aging syndrome in which several features of aging are apparent at birth. We did not find mutations in Lamin A/C (LMNA) gene in four WRS patients, and in particular, we did not find the G608G mutation (GGC > GGT transition) which is associated with most cases with Hutchinson-Gilford progeria (OMIM 176670). These findings suggest that WRS represents a distinct progeroid entity that may be caused by recessive mutations of a different gene. (C) 2009 Wiley-Liss, Inc.
